2019 Infiniti QX50 brakes problems

Filed Dec 30, 2025 · Brakes, Driver assistance · CO

While driving on the highway and using the hands free feature on iPhone, I said, Hey Siri, and somehow it made the automatic braking on my 2019 Infiniti Qx50 engage unexpectedly. This is not the first time it has engaged unexpectedly and there are also instances when the sensors engage without anything nearby.

On 3 different occasions while traveling over 50 mph on the highway, with no other cars around, my Qx50 automatic emergency braking initiated and stopped my car. This is a serious safety issue and I am very lucky I was not rear-ended.

The automatic braking system on my car seems to malfunction when going across the Louisiana/Mississippi bridge. As I was driving the car began to brake but it didn’t come to a complete stop. This put my safety at risk because there were cars behind me and if I would have come to a complete stop on the bridge it would have been a terrible accident. there was a warning issued on my dash while the car was beginning to brake on the bridge.

I was driving around 30 mph crossing an intersection when the Emergency Braking system activated and caused the truck to stop. There was nothing obstructing the vehicle, nor were any pedestrians near. This is the 3rd occurence when this happened.

On may 4, 2019, I tool delivery of a new infinity, qx50 and after 2.5 months of ownership (july 26, 2019 to present), I'm having ongoing / unresolved problems / failures with; audio, lane departure, collision warning w/ sudden stopping, heated / cool seats, infotainment, audio, tailgate, remote door locks, both screens going blank, phone / bluetooth connection, awd, automatic shifting problems and extremely soft brakes that put me thru 2 controlled intersections. The dcu has been replaced 4 times and I still have the same ongoing / unresolved problems. I told the service manager (rudy), to start replacing all the sensors, cms and camera and he refused to do that. My qx50 has been in for service five times (including today, 04-21-2021), for a total of 6+ weeks. The mechanic at infinity, can't replicate any of my ongoing problems / unresolved problems and I have 25 videos, showing what the qx50 is dong and infinity can't fix it. I pay a lot of money for the qx50 and for all the driver safety features, other amenities and it still continues to fail miserably and does not perform as intended. Because of these unresolved problems and ongoing issues, my wife refuses to drive in the qx50 with me. I have asked infinity to buy back the qx50 and they flat out refused. I had to obtain a lawyer.

Dating back to november 2019, my vehicle's automatic emergency braking have engaged 3 times without reasonable cause at speeds that vary from 40-70 MPH. The first two incidents were on normal city roads going approximately 40-45 MPH. The last incident (june 2020) happened while driving on a highway, with no traffic around, going ~70 MPH and my vehicle almost came to a complete stop. The first time I took the vehicle into the dealership, they reset the system. The most recent time they said the incident happened twice to technician and their assumption was the vehicle was not clean enough. I followed up with infiniti consumer affairs and they told me these incidents have happened in other vehicles but do not think the situations are related. With the incident now happening a total of 5 times (and when the vehicle was clean), I do not feel safe in the vehicle and believe there is an underlying issue.

My automatic emergency braking system warned and autobraked my vehicle during my normal driving without any signs of emergency - no cars are in front of me along the whole street. Luckily, no one was hurt. My webcam caught it. If possible, please put attention to this case as all the owners are in danger. It seems that I cannot upload videos but I will be very happy to provide it as an evidence.

This is now the 2nd time this happened!! The car slams on the brakes as if someone is right in front of the car randomly. I was driving around 40mph and no one was in front or next to me, the car randomly slams on the breaks and it takes a few seconds for the car to release the breaks and allows you to start moving again.the sensors go off as if you are too close, when no cars are even in sight. Very dangerous!!!!! This will be killing people, needs a recall asap! Many people have the same complaints online and infiniti does nothing to help
